Decrement operator:
-Denoted by --
-this operator are able to decrease the variable value by 1
Type:
post decrement(i--)
pre decrement(--i)
Example-
i=3;
i--;
//Now value of i is 2
--i;
//Now value of i is 1
program-
#include
int main()
{
int i=10;
cout<<"i="<
i--; // i=i+1
cout<<"i="<
--i;
--i;
i--;
cout<<"i="<
}
output-
i=10
i=9
i=6
-In this program, we start with i=10, then print the value of i after apply decrement operator and result will show in above output.
